How to change the characteristic value in a item of sales order by FM?

Question

Hi experts,
I guess the FM BAPI_SALESORDER_CHANGE can implement my requirement. But I have made many testing program, that's all failed. I don't know which part is not correct. So could you give a very simple sample to me? Just change the characteristic value in a item of sales order, not do any change for other parts. Thanks in advanced.
